PBS is utilizing Facebook's Social Plug-ins on the PBS.org homepage and topic pages. These off-the-shelf solutions provide personalized activity streams and content recommendations to users based on their personal settings. The recommendations widget considers factors such as what you and your Facebook friends have "liked" on PBS.org or interacted with on the PBS Facebook Fan Page. Over time, the recommendations widget will become more intuitive and will display more accurate recommendations. Users will always see the widget, but it will only make personalized recommendations if they are logged into Facebook. If they are not logged into Facebook, the widget will only display generic and popular content recently shared on Facebook.
